Description: BENEFIT CLAIMS This application is a US National Stage of International Application No. PCT/NL2004/00221 filed 2 Apr. 2004, which claims the benefit of NL 1023144, filed 10 Apr. 2003. The invention relates firstly to a multilayer washable material which comprises at least one layer of a textile material and in which the layers are joined to one another by means of an adhesive composition. A material of this type is known from US2001/0001300. The said US application describes a washable textile item and a method for producing it in which layers of textile material are joined to one another by means of a simulated stitching pattern which is formed from a curable hotmelt adhesive whichis applied in the molten form. The layers are placed against one another and the adhesive penetrates into the fibre structure of the layers as a result of the application of pressure, so that after curing of the adhesive the layers are joined to oneanother. A known material of this type has the drawback that the way in which the various layers are joined adopts a stitching pattern character, with the result that wrinkles may occur during use. If a multilayer material of this type is used, forexample, as a washable incontinence underpad, the patient may find wrinkles of this nature very unpleasant and even painful and/or harmful. It is an object of the present invention to provide an improved washable multilayer material of the abovementioned type in which at least wrinkling can no longer occur, and to this end is characterized in that in the interfacial region betweeneach pair of layers bearing against one another there is an adhesive composition in the form of a pattern which prevents wrinkling, and no finishing of the multilayer material, as such and/or of a smaller part obtained therefrom, is carried out. The term in the form of a pattern which prevents wrinkling in this context is to be understood as meaning a pattern shape which on the one hand has a density of joining locations
